Abstract
The aim of this study was to produce deposits of AA 2024-T3 over AA 2024-T3 using friction surfacing, FS, with emphasis on the parameters and its influence on the bonding quality on the center of deposits and hardness along the substrate to the surface deposit. FS is a promising surface technology, which produces fine grained deposits with better properties in wear and fatigue resistance. This process enables to join dissimilar materials without reaching its melting temperatures, known as a solid-state process. Deposit analysis depicted that morphology from the surface of the deposition presents roughness and elliptical shape due to the plasticized metal transferred in layers on after the other for all condition. The results of hardness profile showed that the values are higher at the deposit layer, when compared with the substrate values. Also, refinement grain in deposit layer and completely bonded interface at the center of cross section where observed in all parameters.
